Can`t stop worrying. Removing the request payment button so early, 3 and a half days before the actual payment without posting here why means serious problems. Your team should have warn us before that the button will dissapear so early, so it`s clearly that the sells weren`t as expected and now you don`t have enough funds to pay the uploaders, only a minority who requested the payment much earlier than normal.
So yeah, that`s serious concerning reasons, maybe the end of fiberupload
EDIT: @BlackIce: Last time fiberupload posted here multiple times that the ideal period for requesting payment is two days before, now he didn`t say nothing (not before and not after) and they removed the button at 7/04 at 00:00
